CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No 350,852, dated October12, 1886.

Application filed June 8, 1886. Serial No. 204,490. (No model.)

To all whom it may concern:

Be it known that I, J AMES Turns, of Golumbus, in the county of Franklinand State of Ohio, have invented certain new and, useful Improvements inCar-Axle Boxes, of which the following is a specification, referencebeing had to the accompanying drawings.

My improvements relate particularly to what are known aslubricating-rollers in car- I ers in position.

three are sufficient.

axle boxes.

In the accompanying drawings, illustrating my invention, Figure l is alongitudinal central section of a car-axle box containing myimprovements. Fig. 2 is a horizontal section of the same, showing a planof lubrieating-roll- Fig. 3 is a vertical central section, taken atright angles to Fig. 1. Fig. 4 shows one of the rollers androller-springs detached. Fig. 5 shows one of the skeleton framesdetached.

Referring to the letters upon the drawings to aid a description indetail of my invention, A indicates a light skeleton casting, showndetached in Fig. 5. I prefer to employ three of these castings to benested together, as shown in Fig. 2, so that I may use threelubricatingrollers, B. This enables me to apply my in ventionconveniently and with advantage in the ordinary-sized car-axle box as ingeneral use. It will be practicable to employ fouror even more rollerswith proper supportingframes; but that would be unnecessary, becauseEach one of these skeleton frames, it will be observed, is provided withlugs 0 upon opposite sides of its narrow end, and with recesses D onopposite sides of its wide end. These lugs and recesses serve tointerlock and securely nest the skeleton frames, so that under thestrain of the springs they cannot tilt and get out of place. Eachskeleton frame is alsoprovided at its narrow end with a hook, E, and apartition, F, dividing and projecting upward from the springcoil recessG for the roller spring-coil H. The partition is for the purpose ofstaying and preventing the coil from twisting out of place under strain,and is useful, but it might be dispensed with, although I prefer touseit. The

roller-springs J being hooked upon the hooks E, the coils I will fit inthe recesses G, and the upper parts of the springs will bear the rollersupward against the under side of the journal to be lubricated, while thelower portions of the rollers will travel through the oil in the box andcarry it up constantly and in sufficient quantities to lubricate thejournal. The rollers are kept in their places in the largerollerrecesses L, so that they will not slide endwise and bear againstthe spring ends which support them and cause injurious wear.

Lugs or stays M are provided for the purpose of holding the rollers inplace against end movement and wear of the springs in case the rollersshould rise above the general level of the upper edges of the skeletons.

In one of the skeleton frames, which is designed to be used next theouter end of the axle-box, I have provided a spur, N, which is adaptedto furnish a stop or bearing for the central downward projection, 0,upon the end bearing, P, for the journal, this end hearing being ingeneral character similar to that shown in my United States Patent No.319,643, and that also shown in my pending United States application,Serial No. 197,862. In boxes where the said end bearing is not used itwill not be necessary to provide the spur N, as other means would beprovided forholding the skeleton frames from endwise movement; but Iprefer to use the end bearing for the journal having thedownwardprojection, as shown, and also the spur N.

Having thus described my improvements, what I claim to be new, anddesire to secure by Letters Patent of the United States, is-

1. A skeleton frame or support for use in a car-axle box, provided withthe lugs O and recesses D at their opposite ends, substantially as setforth.

2. A skeleton roller frame or support for use in a car-axle box, havingthe large recess, L, at one end and the hook E and smaller re cess, G,at the other end, with or without the partition F, substantially as setforth.

3. A skeleton roller frame or support for use in a car-axle box, havingthe large recess, L, and lugs or stays M at one end and the hook E andsmaller recess, G, at the other end, with or without the'partition F,substantially as set forth.

4. The combination of three skeleton frames nested together firmly bymeans of lugs and flanges, and carrying the three rollers and Intestimony whereof I have hereunto subtheir springs, substantially as setforth. scribed my name.

5. The combination with a nest of skeleton frames, of the end bearingprovided with a JAMES TIMMS' 5 downward projection, O, and the lug orstay Witnesses:

N on the outer skeleton frame, substantially MARCUS S. HOPKINS, as setforth.
